I continued to research just to be sure that there was nothing about the Raspberry plant or the Blackberry plant themselves that was at all poisonious and I discovered that I was sitting on plenty of free tea leaves for the taking! So began my latest journey in homesteading!
Did you know that raspberries and blackberries operate on a 3 year cycle? The first year a cane (stem) shoots up, the second year it flowers and produces and the third year it dries out and dies? This all happens randomly in a patch so you will see canes with no flowers, canes with flowers and then berries and then other canes that are old and dried out prickers.
Next, I brought the leaves inside where you can wash and pat them dry.
